You can either use a float switch or a float valve to fill your tank, whichever one will fit your situation best.
These switches are installed in the tank into a 2-½ fitting and are used to turn on and off your good pump or your fire bell. This is an electric switch.
These valves go into the top of the tank and are used to fill it. The water reaches the float, and when it reaches a certain level, the water will stop flowing in. We stock 1” and 2” ones.
The CLA valve works like a float valve but keeps your good pump from cycling as often. It features a float valve inside your tank that will travel up and down 1 to 36” or more. This is the only mechanical float valve that gives you a differential from on to off.
